What is 4-AcO-MPT Fumarate?

4-AcO-MPT is a psychedelic tryptamine and an ester form of 4-HO-MPT. It is structurally related to both psilocin (4-HO-DMT) and other 4-substituted tryptamines, and is being investigated for its potential agonist activity at 5-HT2A receptors . As a fumarate salt, it is more suitable for laboratory applications than the free base due to its greater stability and solubility.

⚠️ For scientific and analytical use only. Not intended for human consumption.

Applications in Research

• Pharmacological binding experiments at serotonergic receptors
• Neurobiological behavioral research using cell lines or in vitro models
• Comparative research with other tryptamines such as 4-AcO-DMT and 4-HO-MPT
• Study of structural modification and influence on psychoactive potency

Use & Storage (Laboratory Only)

• Recommended concentration: 1–20 µM for in vitro assays
• 溶解度： Freely soluble in ethanol, DMSO; sparingly soluble in water
• 储存建议： Store in an airtight, dry and cool place (2–8 °C)
